My Windows 7 rebooted continuously...
The other morining, I turned on my Windows 7 RC machine and went to bring some snacks...
When I came back, the machine was rebooting... just after the animation 'Starting Windows...'
And next time, it asked me if I will boot the machine in safe mode...
I chose safe mode and rebooted...
But... it didn't work....
Hmmm.... 'do I have to re-install this RC machine?' 'Is this because of the bug that RC might have?'...
At that point, It occurred to me that I ran 'verifier.exe' the previous day...
So I booted the machine in safe mode and ran verifier again and deleted the configuration that I had made...
Then... my machine came back to the normal state... :)
If your machine suffers the same... please check the verifier...
